不确定

In the first part, the thesis firstly constructs the production possibility sets deduced from constant, nonincreasing, nondecreasing and nondetermined returns to scale. Based on the above point, the thesis systematically deduces the models of DEA which evaluate production efficiency for exogenously fixed inputs and the models of ADEA (Allocative Data Envelopement Analysis) which evaluate cost, revenue, profit efficiencies and allocation efficiency in production possibility sets, and then discusses the solution properties of these mathematics models.

I would reiterate the point that there is an awful lot of uncertainty right now arising in part from the fact we don't know how quickly the credit markets will return to normal and how quickly credit extension will return to normal, and, so in that respect also, I think, we need to be flexible and to continue to watch the situations as we go forward.
